Hi everyone! I found a nickel with what appears to have an error(s) on the reverse. However, I'm not sure how this would be classified. I've looked online for answers, specifically to the markup in green and can't seem to find an answer. Also, I'm new to this so I apologize in advance for any stupid questions or using the wrong terminology. I'm here to learn so feedback is much appreciated. I'm really excited to be a part of this group and can't wait to learn from you all.

Here's what I'm looking for help with and I've marked one of the images to make it easier to figure out what I'm referring to:
1. Yellow Markup: There appears be a crack in the die. Does this look like a crack or like it was scratched after production?
2. Green Markup: I'm not sure what this is called?! There's a circle around the perimeter. Would this be considered doubling? Wrong planchet?
3. Blue Markup: If I didn't have questions about the first two I wouldn't have asked but thought might as well. Do you see any errors here? Or would this be considered normal wear and tear?
I've included pictures of the following:
Reverse- A picture of the entire nickel, close up of the areas in question, a photo with markups to help identify what I need help with.
Obverse- I didn't see any issues but if you see something I may have missed please share. I love learning!
I tried my best to get some good pics. I used the magnifying tool on my iPhone. I didn't even know there was a magnifying tool on my phone until a few weeks ago. If there's anyone that isn't familiar with how to use all you do is push the home button 3x in a row. it works pretty good for photos and if you're on the go. And this might be silly advice - just trying to be helpful!

Thank you in advance for your help!
My best,
Tiffany
